Application filed June 10, 1909. Serial No. 501,225.

To all whom it may concern.

Be it known thatI, EDWARD E. BARRETT, a citizen of the United States, residing at La- Grange, in the countydf Cook and State of Illinois, have invented a certain new and useful Improvement in Loading and UnloadingApparatus', of which the following is a specification. My invention relates to coal handling devices.

It is illustrated in ings, wherein Figure 1 is a front elevation; Fig. 2 a

the accompanying d raw- I cross section showing the bucket on its up ward path; Fig. 3 a cross section showing, the bucket at the bottom of its excursion;

F igg-4 is a detail of the operating bar. Like parts are indicated by the same let- 'ters in all the figures.

A A'are buckets adapted to move ver- -t'ically,'provided each with a hoisting rope A secured to the strap A which is riveted on the bucket. The buckets on their sides are preferably provided with flanges A A between which they receive the vertical guide bar's A whereby the buckets are held to a.

fixed path of travel.

A is a pocket into which the bucket is re-- ceived, A a rim therefor and A an angle bar flange about the bucket which engages the rim when the hucket has reached the lower limit of its downward excursion.

B is a supply hopper with inclined bottoms 'as shown and suitably supported in any framework and foundation, parts of which are indicated by the letters B B B is an opening in the bottom of said hopper beyond which extends the inclined floor 13 This floor is preferably made in sections or provided with an extension B also B The two together form a fixed gravity, chute-for the discharge of the coal from the hopper. I call this chute when arranged as here shown, an interrupted chute. The lowe'rend of'this chute is provided with a discharge end B hinged at- B and normally has secured to its other end the balancing .weight B The weight-of the coal-over comesthe gravity of the weight B? and tbmw$ the hi ge end in the position shown in Fig. 3, but when there is no coal flowing through the inclined chute the discharge end is folded up as indicatedtin Fig. 2. 3

G is an operating bar each end of which is provided with a double link C which carries each two grooved rollers C C one above and one below the bar. These rollers are adapted to engage, by receiving into their grooves, the vertical guide rails C 0 To the upper end of each link C is secured an operating rope D. This rope passes upwardly over a pulley D and then downu'ardly about anarrow drum D on the end of the measuring gate to which it is secured at the point I). When the bucket descends, its projecting flange A? engages the bar C and forces it downwardly thus drawing upon the ropes D D and turning the measuring gate around, until as indicated in Fig.

3, ithas cut oil the supply of coal on the hopper side and discharged the load of coal in the measuring gate into the inclined chute, whence it passes into the bucket in the bottom of the pocket.

Attached to eacli of the drums at the:

point E is a rope E which passes along the pulley E thence upwardly and along the pulley E thence across to the adjacent hoist over a pulley E thence down along the pulley E and' thence to a similar point of attachment on the drum of the neasuring In like manner another rope F is attached in a similar position 'on the drum "whence it passes over the pulley F the pulley F thence across to the other hoist-'where it misses over the pulley F and thence down l over the pulley F and thence to a similar point. of attachment on the drum of the measuring gate associated with that hoisting shaft. 1

Assuming now,- that when the bucket in one shaftisinthe position shown in Fig. 2 with its measuring gate loaded and ready to be operated and that the bucket thereupon descendsto the-position shown in 3 thereby as previously described, rotating this measuring'gate until the gate has assumed the positionof Fig. 3, it will be clear that this rotation of the gate, which is in a counter clockwise direction, winds up the ropes E and'F with the result that the gate in the opposite shaftis rotated in-the Eo'p posite direction from the gateshown in Fig. 3. In otherwords, whenthe bucket in one shaft'descends, it rotates its associated gate in a given direction to cause it to discharge-and by the same action it rotates the .gatein the other shaft in the opposite sense {so as to bring it into position of loading.

The tv'vodrums are therefore at a given moinentin the position, shown in Figs. 2 and 3,

1o awe loaded and acting as a gate, the other mpty and acting as a gate. This condition as reversed by the downward movement of ihe bucket. which simultaneously moves both gatesin the manner suggested.

7 G is a shaft mountedon the bearings G G on thefframefpi eces provided with spokes Gr (ii-end pieces G G and a periphlate G which incloses about one-half ri of this cylindrical measuring gate, the other 7 half open.

' .:'J S the upper part and J the sides ofthe ease in which the measuring gate is mountj ed, the-lower part of such case being formedfrom the hopper to the bucket consisting of a two separate fixed inclined chutes and a niovabl'e dis'charge end, the rotatable measefl gate interrupting such inclined iehutesjfor separating two of its sections, ineans'j-whereby the two measuring "gates are' simultaneously operated in opposite senses, and neans whereby the motion of the crates the gates.

efand operation of my invention will-bes'ufliciently evident from' what-has already-been said. When a given bucket descends it finds the measuring gate of its shaft'loaded and in the position indicated Fig. 2 bemuse that gate has been brought tdthat position by the' action'of the other bucket in the other shaft. \Vhcn the bucket questiondescends, it strikes the operating 5. barand'rotates its associated gate so as to receive its supply of coal from such neasuring gate-but by the same action and through the ropes, it transmits power to the otherineasuring gate, moves it in the oppositesense, turnsit so that its open side is toward the hopperand its peripheral plate toward the shaft whereupon such other gate fills and remains in the position shown in 2. hen the operating bucket rises,

as the discharge end rises and thus the opera- "suitable for any flowing solid.

tion continues, each'descending bucket alternately loading and setting the measuring gate for the other.

It will be understood of course that the measuring gates are proportioned so, as to supply the desired amount of coal to the bucket. It will be observed that the peripheral plate acts all thetime as a gate and that it is first on the hopper side and then on the shaft side. It willa'lso be observed that this' plateoperates as a chute to a certain extent discharging the coal from within the measuring gate down over the-- its lower end, thus interrupting and bridging the space between the two fixed chutes B and-B. I v Ihave described my device as applicable to the handling of coal but of course it is l have also described and illustrated my improvements in connection with the two buckets and two shaft structures but obviously many important features of mymventi'on are fully, utilized in a single bucket apparatus. The particular means of communlcat ng motlon from the bucket to the measuring gate is here shown as suitable fora two shaft and donble bucket structure. p
